HD7700 Black Screen - Win 7 17.7.2

So my problem has not been solved yet. I don't know when I can solve it. The problem is playing games without a black screen. For example, the best speed OL, the best speed 17. Mine is an independent HD7700-4G video card. I want to switch to independent graphics cards, don't you think so? OK, now I offer all the information I know. 1:AMD video card type: HD7700-4G

So, with these, do you know how to solve it? Is this AMD card driver version unsuitable for me, or is it unstable? Which version of the AMD graphics card drive didn't lead to a black screen? I think you should discuss the solution with other colleagues, thank you.

We have updated the title of this discussion with relevant details to better describe your issue.

From seeing various sites concerning the power requirements for HD 7700 series card you should have a minimum PSU of 450 watts. Does the card have a Power connector to it and is it connected to the PSU?

Are you talking about video card power lines? I don't have a connection to the video card power line. I don't think HD7700 needs the power of 450W, because I use Lu master power check to see that the power consumption of HD7700 is not large. Only 80W, using 450W, I don't think it's possible.

The only cards that don't need connectors on the 7700 series is the 7730 & 7750. They both recommend a minimum of 350 watt PSU to run. This according to Kingfish link from above : PSU REQUIREMENTS - RealHardTechX . The card may only use 80 watts at idle but during heavy load, the wattage increase a lot plus the power used by the motherboard, CPU, PSU, RAM, Hard Drives all add to a minimum PSU of 350.

You mentioned your AMD is a HD 7700 4g. When I google that card, it comes up showing a HD 7770 AMD graphics card that does need a Power connector and does require a 430 PSU minimum supply. So unless you didn't post the correct model of your AMD GPU card, You need to install a more powerful PSU.

If you do have a HD 7730 or 7750 AMD Graphic card, Obviously, the PSU you have is minimum to operate normally but may not be enough when the GPU card and the system is under heavy load. Which may explain why your screen goes black during game playing.

You opened a similar thread in May, and was told the same thing as mentioned here. You need a more powerful PSU. Do you remember this thread you opened in May : Video card driver problem

I can't figure out why HD7700 is higher than HD7750 needs Is the black screen connected to the video card without wires? NVIDIA graphics card series needed up to so much? My previous video card was GT630, and when using that video card, I played any game, never black screen, including GTA5.

I want to be with AMD global settings inside the power control settings have a certain relationship, because I looked at the set is -20%, then I transferred to +20%, I want to test whether this situation will appear black, you feel with the Never mind?
